Kewa flowers

 

My little Kewa salsoloides plants have been flowering continuously for months. Very pretty, pale pink and with a sweet floral fragrance. That is as near as I can pin it down, it evokes memories of other fragrances but I can't say which ones exactly. Perhaps the candied notes of Night Phlox (Zaluzianskaya capensis) flowers but not so much the sugared almonds of which the Night Phlox remind me. More flowers keep developing, providing a constant display.

Parakaryon myojinense - unique wonder or misleading mash-up?

I have just added to the Wikipedia entry for Parakaryon myojinense. This name was given to a single specimen found on a polychaete worm from a hydrothermal vent on an underwater volcano south of Japan. The discoverers claimed it was a new domain of life, neither prokaryote nor eukaryote. No other specimen has ever been discovered.

I added some extra bits to the Wikipedia article that I thought could give readers a clue to the probable overenthusiasm that inspired the claim that this is a new form of life. Unfortunately, no microbiologists seem to have commented on the find, other than the team who discovered it. A pop biochemist called Nick Lane got very enthusiastic about it. Otherwise, there is a strange lack of any comment on the internet, positive or negative.

I had to stop myself commenting further as Wikipedia does not allow opinions unless they are properly citable and I am certainly not a microbiologist. I had to get my comments down somewhere. Who knows, someone might find this little rant if they do a search. This specimen just doesn't seem to live up to the interpretation that the authors proposed. Most of what I have written is off the top of my head, not as polished as my usual long articles.
